Cost: $15 Buy full version       Trial version       Publisher: Numerical Mathematics     Descriptions Functions: Easy to use, intuitive program to visualize and study functions of one variable in a defined interval to find roots, maxima and minima, integral, derivatives, graph. You can predefine constants and specify the error bound for the results. It can fully explore intervals to search for solutions. Handles trigonometric and hyperbolic functions among others. Results, including the graph, can be saved or printed. You can also copy the graph to the clipboard, which you can then paste where you please (Word, Paint, etc.). You have one-click control of the graph with zooming, panning, centering, etc. Includes a help file with instructions, example and methodology.
